784 Hydrophyllaceae Polemonium 



and I highly recommend it for ornamental planting. It has sown itself 

 in our garden for many years. 



S. Dak. to Ark., southw. to Fla. and Tex. ; naturalized northw. and eastw. 



7017. POLEMONIUM [Tourn.] L. Polemonium 



1. Polemonium reptans L. Creeping Polemonium. Map 1691. Our 

 manuals call this species Greek Valerian. Frequent to common in deep 

 humus throughout the state, although there are no specimens from La- 

 grange or Steuben Counties. It is more abundant when associated with 

 beech and sugar maple and white oak and red oak. It is rarely found in 

 springy places but sometimes it is found in low, flat woods in the south- 

 western part of the state. It is rarely found in the open along roadsides 

 and railroads, although when introduced into cultivation it thrives in the 

 open. 



Two old pioneers told me that the root was a diuretic and a specific for 

 kidney disorders. 



N. Y. to Minn., southw. to Ga. and Kans.
